Our son gave us one for xmas and I love it. I do the cooking now so I have used the air fryer a lot. I buy shoestring potatoes at the store and fix them about 20 minutes shaking them often. I don't use oil at all, that's the point of the air fryer , you don't need it everything comes out crispy and browned on its own. I spray the inside of the fryer with pam so nothing sticks and clean up is a snap. I recommend that you do French fries first to see how it works. I have fixed pork chops, steak, tater tots, fish sticks, chicken nuggets, and green beans. It is great for warming things up, microwave makes things soggy this gadget makes them crisp. If you do use oil (you don't have to) brush a little oil on the product being fixed. Don't pour oil into it you need that space at the bottom to circulate the heat. Read the instructions that come with it. If there is a downside it is that it doesn't hold a lot of anything at one time.
